Understanding the Scientific Method Essentials

The independent variable is the cause in the experiment that is being manipulated or changed.

The conclusion should summarize what was learned from the experiment, include both the independent and dependent variables, avoid specific numerical results, and focus on trends and general findings. It is written in past or present tense since the experiment is complete.

Example: 'The more sugar added to the dough, the higher the bread will rise.' Cause: Amount of sugar, Effect: Bread's rise

Recognizing these roles helps in framing the aim, hypothesis, and conclusion correctly and ensures the experiment is scientifically sound.

A hypothesis should be a prediction of the experiment's outcome, presented as a clear statement and not a question. It includes both independent and dependent variables and is written in future or present tense.

The aim states the purpose of the investigation and is written before conducting the experiment. It should include both the independent and dependent variables.

Example: 'When salt is added to ice, it melts faster than without salt.'

Example: 'A test was done to determine the best baking powder for a high cake.' Independent Variable: Type of baking powder, Dependent Variable: Height of the cake
